shouldbc understood. that the devices of our invention may be applied toother styles of writing machines.

The frame of the machine comprises a base 1, corner posts 2 and a topplate 3. Type bars 4 are pivoted to hangers 5 to swing upwardly andrearwardly to strike against the front face of a platen 6. The type barsare segmentally arranged and each bar is connected to a pull link 7, therear end of which is pivoted at 8 to an upright sub-lever 9 connected inthe usual manner to an associated printing key (not shown). Fixedcarriage rails 10 are 7 secured to yoke-like brackets 11 which areattached to the top plate of the machine. These fixed rails are groovedon oppositely disposed faces for cooperation -withantifriction balls 12which are likewise received in oppositely disposed grooved faces in arear carriage bar 13.

The carriage comprises the bar 13 and end plates or arms 14 providedwith bearings to receive a platen shaft 15 on which the platen 6 ismounted. Arms 16 are pivoted to the endbarsof the carriage and areconnected at their rear ends to afeed rack 1 7 which meshes with afeedpinion 18 secured to the forward end of a shaft 19 which turns in abearing 20 secured to the top plate of the machine. The shaft 19 isoperatively connected at its rear endto an escapement wheel 21 by theusual pawl and ratchet mechanism (not shown). The escapcment wheelcooperates with feed dogs 22 carried by a dog rocker 23 pivotedat 24 toa depending bracket 25 secured to the top plate of the machine. The dogrocker has a forwardly projecting arm 26 to which the upper end of alink 27 is connected, the lower end of said link being connected in theusual manner to the universal bar frame (not shown) so that eachactuation of a printing key is cll'cctivc to actuate the dog rocker toafford a letter space movement of the carriage in the direction of thefeed under the control of a s )ring drum 28 connected to the carriage lstrap or band29. The rear cross bar of the carriage is' provided withrcarwzudly oxtonding bracket arms near each end thereof, said bracketarms being provided with l) l.1lIlZS for arock shaft or column stoprod}? This slop rod is slotted on opposite sides thoirof as indicaicd at3; for

. cooperation with "bifurcated adiusiablmcol- Cir iy a

lCb

umn stops 33 which may be attached to the column stopv red at any pointin the length thereo fu' The upper fixed rail 10 has a bracket 34secured thereto by screws 35. Rearwardly projecting arms 36 project fromthe. bracket and are perforated to form hearing Openings for the recetion of a short v rock shaft 37 to which a ta ulator stop 38 is securedor forms a part. A coiled spring 39 surrounds the shaft 37 and issecured at ne end"40 to the sto 38 and at its opposite 1d 41 to one ofthe bracket arms 36. The pressure of this spring is exerted to normallymaintain the stop 38 out of the path of the stop portions 42 of thecooperating column stops 33 as shown-in Fig. 1. The stop 38 is providedwith a tail piece 43 which extends, on the opposite side of therockshaft fromthe stop 38 and is notched at 44 for 006 eration'withanactuating device 45. A nger 46 projects forwardly from the sto 38 andinthe normal osition thereof is a apted to bear upon the liracket '34 asshown in Fig. 1 to arrest the tabulator stop 38 in its normal position.The actuating device 45, as shown 1n Fig, 2, comprises a frame-likemember with an opening in the center thereof through which the feedpinion 18 and bearing 20 extend, the upper end of the member 45terminating in a, finger 47 which directly co-acts with the notch 44 inthe tail-piece 43 of the tabulator stop. Each side arm of the member-45is slotted at 48-for the reception of a headed pin 49 which is connectedto a carriage releasing device 50. The lower stem-like member 51. of thedevice 45 is pivotally connected to the left-hand end of a lever 52pivoted at 53 to a bracket 54 I which extends downwardly from the toplate. The right-hand end portion of the ever 52 is provided with anupwardly extending fin er 55 which constitutes a stop that normaTlybears against the top plate of the machine to limit the movement ofthelever and the parts connected thereto in one direction. The right-handend of the lever post of the machine.

to a 52 is pivotally connectedat 56 to a depending link 57, the lowerend of which is pivoted at 58 to a rearwardly extending arm 59 of athree-arm lever ivoted-at 60 to a bracket 61 secured to t e rearright-hand corner An upwardly extending arm 62 of said leveris pivotedat 63 to a forwardly extending actuating link or rod 64 which at itsforward end extends through openings in the right-hand forward cornerpost and is provided with a finger piece or utton 65. A third ordownwardly extending arm 66 of the three-arm'lever extends point belowthe printing keys of the machine, and the lower end of said lever arm"is provided with a laterally projecting abutment or locking pin 67. Theconstruction is such that when the operator ushes the key 63*65rearwardly the three-arm ever 5962--- 66 will be vibrated to pull downthe link 57', rock the lever 52 and elevate the actuating device 45 toturn the tabulating stop 38 on its ivot into the path of the columnstops 33.

1? release key 68 is connected to the forward end of the release keylever 69 pivoted at 70 to an arm 71 secured to the baseof the machine.The lever 69 extends rearwardly of its pivot and cooperates with anexpansion spring 72 which bears at one 'end against the rearend of thekey lever 69 and at its other end against the base of the Inachine inorder to restore the release key lever 69 and the parts connectedtherewith to normal osition. A laterally projecting pin 73 pro ects fromthe key lever 69 and extends into a slot 74 formed in a sub-lever 75pivoted at its forward end as at 76 to a laterally projecting stud77which extends inwardly from the base of the machine. The rear end ofthis sub-lever is pivoted at 78 to an upwardly extending link 79 whichextends through an opening in the baseof the machine and is connected atits upper end to the right-hand end of a carriage release lever. 80. Theconnection between the link' 79 and the lever 80 is effected by theupper end of said link passing freelyv through an opening formed in thelever,

nuts 81 being threaded onto the up .er end of the link 79 above thelever 80. coiled spring 82 surrounds the link 79 and bears at its'upperend against the Washer 83 which surrounds the link and bears against thebottom of the lever 80,- the lower end of the spging bearing against thebase of .the mac he The pressure of this spring is exerted to force theright-hand end of the lever 80 upwardly and to cause the stop orprojection 84 thereon to bear against the top late of the machine andthus maintain the ever 80 and the releasing device 50 connected theretoin their normal positions. The left-hand end of the lever 80 is pivotedat 85 to a de pending stem 86 formed on the releasing device. 50. The uer end portion of the releasing device is ifurcated as shown in Fig. 2to straddle the shaft 19 and the bearing 20 thereof and is bent forwardat the upper ends of the arms of the bifurcated portion as indicated at87 in Figs. 1,3 and 5. These portions 87 constitute rack lifting shoeswhich extend beneath the feed rack of the machine and are adapted tocooperate therewith when the releasing device is elevated, to turn thefeed rack around the pivots of the arms thereof in order to disenga ethe latter from overlap the sub-lever 75 and to form a contact shoe 94with which the'lower edge of the release lever 69 is adapted tocooperate. The laterally projecting locking pin 67 extends beneath thesub-lever. 75 and the locking latch and. supports the weighted end ofsaid latch as indicated in Figs. 1 and 2. The contact face 95 at thelower edge of the sub-lever 75 with which the locking pin 67 cooperatesis substantially in an arc of which the pivot-60 is a center so that thesub-lever 75 is normally locked against depression by the locking pin 67but said pin is free to move when the key 65 is actuated from theosition shown in Fig. 1 to that indicated in igs. 3 and 4 where thelocking pin registers with the slot 93. This movement of the thre"earmlever andlocking pin to the osition shown in Fig. 3 from the position sown in Fig. 1 is effective to elevate the rear end. of

the latch. by the cooperation of the pin 67 i with the cam edge 96 ofthe latch until the notched portion adjacent to the locking shoulder 91is reached when the rear end of the latch 89 will drop to the engagingposi tion shown in Figs. 3 and 4. In this position the shoulder 91engages the rear side of the locking pin and locks the three-arm leverand the parts connected therewith against movement.

It will be observed that the locking shoulder 91is substantially in anarc of which the pivot 88 is a center and that when the parts are in thelocked positions, represented in Fig. 3, the locking pin 67, the pivot88 and the pivot 76 are substantially in a straight line so that the.tendency of the three-arm lever 596266 and the parts connected therewithto move to the normal position is resisted by a dead center pull 'on thefixed pivot 76. On the other hand, when the parts are in the normalposition shown in Fig. 1 a' depression of the releasekey 69 and theparts connected therewith is resisted by the lever 596266 effecting adead center pull against its fixed pivot 60 so that the release key 68and. the parts connected therewith are normally locked against operationand cannot be moved until the tabulator key 65is actuated. When thetabulator key is actuated, the tabulator stop 38 will be moved intoc'o6perative relation with one of the col- .umn stops 33 and the partswill be locked in the operative position by the gravity latch 89.. Theact of operating the tabulating mechanism is eflectirre to move thelocking pin into register with the slot 93, thus automatically releasingthe release key 68, the

' sub-lever 75 and the parts controlled. thereby so that the release keymay at this time be depressed. The effect of depressing the release keyis to depress the rear end of the ing device and allowing.thccarriage tobe column stops is brought into contact with. the'tabulator stop 38. Thefirst portion ot the depression of the release key lever 69 is effectiveto bring the lower edge thereof into contact with the shoe 94 on thelocking latch and to turn said latch on its pivot 88 out of lockingengagement with the lockingpin 67 as shown in Figs. 5 and 6. The lockingpm will be freed from the latch at the full depression of the releasekey 68 and. will move 5 when released from the locking shoulder 91 intoengagement with the contact wall 92 of the slot in the sub-lever asshown in Fig. 6, so that when the carriage release lever 68 is releasedthe pin 67 cannot be again enlever is effective to resist the movementof the other lever, and that each of said levers is effective to lockthe other against operation, and that an actuation of one lever isefiective to release the other.

The mechanism described assures the correct operation of the parts andassures the proper interpositioning of the stop before the carriage canbe released.

In the operation of the devices, the tabulator key 65 is first pushedinwardly thus automatically releasing the carriage releasing mechanismfrom looking engagement and locking the projected tabulator stop 33incooperative relation with one of the column stops; that is to say, in aposition where the stop 38 is in the path of the column stops andiscoperative to co-act with one of them when the carriage is released.The release key 68 is then depressed, thereby releasing the carriage andaffording a movement thereof until one of. the column steps is broughtinto engagement with the tabulator stop 38. When tabulator stop 38 willbe automatically released from its locked position and the parts. willbe restored to normal position when the release key will beautomatically locked until the tabulating, key is again actuated.

From the foregoing description it will be understood that the locking ofthe stops in cooperative. relation is effected independently of and isnot dependent upon pressure maintained upon the finger key of the release, and that the locking of the release is,

efl'ected independently of and is not dependout on pressure of thefinger maintained on the key of thetabulator and that the release keycannot be actuated until the tabulator is actuated.

pressure on the release key 68 is released the For the purpose of ourresent invention the character of the tabu ating mechanism employed isimmaterial and from certain aspects of the invention some features ofthe invention may be employed without others.
